A document or application is considered accessible if meets certain technical criteria and can
be used by people with disabilities. This includes access by people who are mobility impaired,
blind, low vision, deaf, hard of hearing , or who have cognitive impairments. Accessibility
features in Adobe Acrobat, Adobe Reader and in the Portable Document Format (PDF) make
it easier for people with disabilities to use PDF documents and forms, with and without the aid
of assistive technology software and devices such as screen readers, screen magnifiers, text-to-
speech software, speech recognition software, alternative input devices, Braille embossers, and
refreshable Braille displays.
